Hello all. I have an issue that I’ve never experienced before. I have a hen that has been completely alienated from the flock. I noticed she was staying in the hen house all day long. At first I thought she was sick. After a day of giving vitamins and watching her closely I came to the conclusion she’s not sick. She’s eating and drinking when I give her both, and her color is good and she is acting normal, and still laying. I put her outside with the rest of the flock and they went after her obsessively. This hen has been with the flock for almost two years with no prior troubles up until this last week. What could be going on? I’m stumped!
